somebody on the forums found them if i remember rightly. 50A forwards/ 20A reverse. was mainly down to cost (from ebay). my plan is to build something fairly cheap then improve it over time with better components. thats the reason for the empty-ish space inside i.e. for motorised weapons. the plan is to have the receiver then connect each side with servo y leads to the ESCs (with the mixer and failsafes in there).
